Overlapping area is at least the 80% of electrodeless area；Specifically, discontinuous hydrophilic cofferdam can be overlapped with electrodeless area, discontinuous parent
The overlapping area in water cofferdam and electrodeless area is that electrodeless area, i.e. overlapping area account for the 100% of electrodeless area；Or electrodeless area
Inside the region in discontinuous hydrophilic cofferdam, the region in discontinuous hydrophilic cofferdam is more than electrodeless region, now, discontinuous parent
The overlapping area in water cofferdam and electrodeless area is also electrodeless area；The third situation, discontinuous hydrophilic cofferdam is less than electrodeless area
Or discontinuous hydrophilic cofferdam partially overlaps with electrodeless area, now, the overlapping area in discontinuous hydrophilic cofferdam and electrodeless area
Need to ensure to be at least the 80% of electrodeless area.With reference to Fig. 3 and Fig. 4, Fig. 3 is a kind of bistable electro wetting substrate knot in the present invention
One specific embodiment top view of structure, illustrates that situation of the edge shape in electrodeless area for arc, and discontinuous hydrophilic
Cofferdam is less than electrodeless area, and the edge shape in discontinuous hydrophilic cofferdam is also arc；Fig. 4 is a kind of bistable electro profit in the present invention
The another specific embodiment top view of wet board structure, the edge shape for illustrating that electrodeless area is the situation of linear, and
And discontinuous hydrophilic cofferdam is completely superposed with electrodeless area, the edge shape in discontinuous hydrophilic cofferdam is also linear.In addition, this
Discontinuous hydrophilic cofferdam is provided with the gap no less than one in invention, is used as the motion path of first fluid (ink).Such as Fig. 3
In, the hydrophilic cofferdam of arc is included in 19,21 and 22 this 3 gaps, Fig. 4, and 24 be gap, 20,22 and in the hydrophilic cofferdam of linear
23 be cofferdam region, further, and the height in hydrophilic cofferdam is 200nm~50um；The width in hydrophilic cofferdam is 1um~50um；
The width in gap is less than 30um, to ensure ink in the presence of surface tension, is localized when without electric field action in two
One of electrode zone.Further, the material in hydrophilic cofferdam and the material of pixel wall are identical, can be used as pixel using photoresist
Wall and the material in hydrophilic cofferdam, or other materials more more hydrophilic than drain insulating layer, its be covered in the first region and
On electrodeless area between second electrode area, its scope is identical with electrodeless area, or more somewhat larger than electrodeless area, Huo Zhelve
It is smaller.If Other substrate materials, then it can be completed with same lithography step.Then by the present invention, electric profit is not only realized
The bistable display of wet display；Also, because hydrophilic cofferdam and pixel wall can complete for same lithography step, do not increase original
Some processing steps.
By taking the hydrophilic cofferdam of arc as an example, with reference to Fig. 5, Fig. 6, Fig. 7 and Fig. 8, Fig. 5 is a kind of bistable electro wetting in the present invention
The pixel opening sectional view of board structure, Fig. 6 is a kind of pixel unlatching of bistable electro wetting board structure in the present invention
State top view, Fig. 7 is a kind of pixel closed mode sectional view of bistable electro wetting board structure in the present invention, and Fig. 8 is this
A kind of bistable electro soaks the pixel closed mode top view of board structure in invention, when to the application of second electrode area 10 voltage
When, the first fluid 15 in second electrode area 10 can be extruded into the first region 9 (as schemed by the gap between the section of cofferdam
Shown in 5 sectional view and Fig. 6 top view), i.e. first area 16.Because cofferdam section is hydrophilic and oleophobic performance and first fluid
15 surface tension of liquid effect, when the voltage is removed, liquid is locked in first area 16, and now first area 16 is presented
Ink colors, and transparent or substrate color is presented in second area 17, substrate color can be white；Now, pixel is integrally shown
For the substrate color of second area 17, pixel is in opened condition.
When applying voltage to the first region 9, first fluid 15 (ink) is due to the driving of electric field, in first area 16
First fluid 15 can be extruded into by the gap between cofferdam in second area 17 (such as Fig. 7 and Fig. 8), when removing electric field
When, due to the stop of ink surface tension effect, and hydrophilic cofferdam, it is difficult to return to first by the smaller space in hydrophilic cofferdam
Electrode district 9, i.e. ink rest on second area 17.Now ink colors are presented in second area 17, and first area 16 is presented
Bright or substrate color, pixel is indicated generally at the ink colors of second area 17, and pixel is in closed mode.
Above is the preferable implementation to the present invention is illustrated, but the invention is not limited to the implementation
Example, those skilled in the art can also make a variety of equivalent variations or replace on the premise of without prejudice to spirit of the invention
Change, these equivalent deformations or replacement are all contained in the application claim limited range.
